Official Ctrip Technology account, sharing and discussing growth.
This article explains how to improve CSS animation performance by understanding the browser rendering pipeline, using GPU‑accelerated transforms, avoiding costly properties and complex selectors, leveraging will‑change and requestAnimationFrame, and preferring CSS over JavaScript for smoother, lower‑latency visual effects.
This article examines common timeout problems in microservice architectures, identifies root causes such as connection and socket timeouts, and presents ten practical optimization techniques—including setting appropriate timeouts, rate limiting, cache improvements, thread‑pool tuning, GC and JIT adjustments, NIO async programming, host migration, and network checks—to enhance system stability and performance.
This article describes a cross‑platform solution that enables a single set of Web component code to be shared across Native, React Native, and mini‑program environments by leveraging Web Components, environment‑aware builds, and bridge communication, thereby reducing development effort and accelerating release cycles.
This article presents a graph‑neural‑network driven, unsupervised approach that builds heterogeneous user‑feature graphs, learns node weights, constructs user‑user similarity graphs, and applies threshold‑based clustering to identify abnormal registration clusters for fraud detection in Ctrip's business travel platform.
This article presents Ctrip's end‑to‑end solution for precise ad‑inventory forecasting using an LSTM model combined with entity embedding, covering data preprocessing, K‑means clustering, model architecture, offline‑online incremental training, early‑stop mechanisms, evaluation metrics, and Python service deployment.
This technical guide details how to set up iOS dependencies, publish KMM libraries, build a GitLab CI/CD pipeline, and resolve common integration problems for Kotlin Multiplatform Mobile projects, providing code examples and best‑practice recommendations for mobile developers.
This article describes the design and implementation of a DIY product card system that decouples UI and logic, enabling product teams to configure and render customizable, cross‑platform card templates via a low‑code platform, reducing development effort and improving click‑through rates.
This article describes how Ctrip's Train Ticket Android project reduced its clean Gradle build time by more than half using a module‑AAR approach, custom dependency substitution, Maven publishing, and automated tooling, while detailing the challenges, code changes, and performance results.
This article analyzes the challenges of stitching multi‑modal transport routes in Ctrip's backend, identifies performance bottlenecks through monitoring, profiling and benchmarking, and presents a series of optimizations—including code refactoring, indexing, multi‑way merge, multi‑level caching, preprocessing, multithreading, lazy computation, and JVM tuning—that collectively reduce latency and resource consumption.
This article shares the team’s practical experience and solutions for embedding H5 pages in mini‑program WebViews, covering platform differences, communication mechanisms, onShow handling, common pitfalls, login‑state synchronization, payment integration, and the use of WebSocket to achieve real‑time cross‑page updates.
